cifs/smb is a BAD idea to use for file update , better work locally and overwrite it. 
fish is a wrapper , try using sshfs (still bad idea , but safer) as it will fail in more clear way.

In practise I found the safest way to collaborate over network  was git-svn  (keep your pitchforks aside git is great but don't have per file locks that are so needed for binary files), or just to work locally and then overwrite the original file.
Multi connection edits over the network is a guarantee for a headache later.

Both fish and cifs/smb have an underlying protocols, which errors are translated, so some type of errors in ssh/filesystem would be translated to no permission  in KIO level (your ui) where the original problem was no access for example (I personally fixed such case in one of the cifs versions many years ago).
There was a set of errors that can happen due to many problems , but you use a standard errno to bring it up, sometimes we (developers) make bugs and choose not the best option (sorry in advance).

This can happen if file modif date is changed between your file and networked drive file, to verify you can check the modif date on the network file and compare it to your original modif date.
